From Definition 4, Definition 5, we propose the directed information graph to represent the causal dependence and instantaneous coupling ... WebBuilding on the recent advance of the Marko-Massey theory of directed information (Massey, 1990), we present the principle of maximum causal entropy (MaxCausalEnt). It prescribes a probability distribu-tion by maximizing the entropy of a sequence of vari-ables conditioned on the side information available at each time step.
